Answer:
y=11x-55
Step-by-step explanation:
First, write your current equation: y=11x+b. Next, plug in one of the coordinates to your equation to find the y-intercept. It should look like this: 0=11(5)+b. Multiply 11 by 5 to get 55. This is what you have now: 0=55+b. Subtract 55 from both sides to get your y-intercept of -55. Go back to your original equation and plug in your y-intercept. This is your final answer: y=11x-55. Hope this helped!
Answer: The area of the lake is actually 182 square miles 1 inch represents one side 3 miles long the other side is also 3 miles. 3×3=9 square miles. 1 Square Inch on the map represents 9 Square Miles.
Step-by-step explanation: If the area on the map is 18 square inches, and each square inch represents 9 square miles, multiply 18×9=182 to get the area of that big lake.
